Title: Equipment and method for estimating rotor position of synchronous motor
Inventor: INABA HIROMI
IPC: H02P6/18
Filed: 1998-08-24
Abstract: PROBLEM TO BE SOLVED: To estimate the position of a rotor after power stoppage or a system trouble for a synchronous motor which cannot be provided with a rotor position sensor. SOLUTION: A rotor position estimating equipment which fixes the rotation of a rotor of a synchronous motor 6 and applies a plurality of instruction voltages 226 of different phases to the motor widings of the synchronous motor 6 and estimates the position of the rotor based on the response time of each response current IdM detected for each of the instruction voltages. In this case, the phases applied to a plurality of instruction voltages are set to a plurality of phases obtained by dividing the entire circumference of the synchronous motor 6 into the same angles. The position of the rotor is calculated based on the phase for which the response current of the maximum response time has been detected. The response time is measured by split plot method or a pattern matching method, so that the measuring times can be limited.

Abstract: PURPOSE:To grasp easily the attendance state of crews of diagram numbers set in the order of attendance time and also to arouse a roll call, by providing an alternating display panel to arrange a specific number of diagrams in the order of working start time points for display and also to display the attendance state of the crews. CONSTITUTION:When the alternating chart information on that day is supplied to an input circuit 11 from an input device 2 for alternating chart information, a CPU 12 applies the arithmetix processing to the chart information. Then the diagrams are rearranged in the order of the working time points on that day and stored temporarily in a memory 13 and at the same time delivered to an output circuit 14 to be displayed on an alternating display panel 5. An attendant crew puts his card into an ID card reader 3. Thus the attendance information is supplied through the circuit 11 and the CPU 12 reads out the alternating chart information on that day stored in the memory 13 to apply the arithmetic processing to the information. Then the attendance information is written to the memory 13 and also displayed on the panel 5. Here a crew at rest detected by a working start/end detector 4 is displayed on the panel 5 in accordance with the next working time point. A keyboard 6 supplies the code numbers of names of the absent crews or the code numbers of the spare crews for change and confirmation.

Title: Manufacture of alkaline storage battery
Inventor: SHIOI YOSHIYUKI
IPC: H01M2/18
Filed: 1990-09-11
Abstract: PURPOSE:To eliminate pole plates coming into contact with each other even if winding shift occurs in a group of pole plates and thereby eliminating short- circuiting and reduce defective rate remarkably by providing separators which are sufficiently higher than the pole plates. CONSTITUTION:With regard to the difference between a separator 5 lengthwise width and a positive electrode plate 6 lengthwise width when the lengthwise width of the separator 5 is equal to or more than the lengthwise width of a pole plate 6, if there is too much difference, a harmful effect occurs at a winding work and workability is impaired. Also, if the difference is too little, the pole plate 6 is exposed from the separator 5 and there is fear of short-circuiting. Accordingly, a separator lengthwise width is generally made (X+alpha)mm against the positive electrode plate height Xm, but alpha=2-5mm. That is, in the case of making a positive electrode plate height Xmm, a separator width is made X+2-3mm in a fold portion direction and X+4-5mm in an opening direction (the end side of the winding).

Title: Signal processor
Inventor: MATSUNAGA KEIJI
IPC: H03H17/02
Filed: 1998-08-11
Abstract: PROBLEM TO BE SOLVED: To reproduce the signal components of a level equal to quantization noise, etc., or a fine level smaller than it at the time of reducing the quantization noise or quantization distortion from a digitized audio signal (digital audio signal). SOLUTION: In the case that tonal components tends to attenuate and a assumed tonal component level is not higher than the prescribed threshold value level, an attenuation arithmetic circuit judges the tonal components to be fine and music components to be buried in quantization noise to make the tonal component assumed by a tonal component assuming part 5 effective. Then, data in a band equivalent to the assumed tonal component is made zero and prescribed band signals excepting for the tonal components are attenuated to give a reverse FET part 7, which inversely transforms it to a time axis waveform. In addition, an adding part 9 adds it with a waveform from a reverse FET part 8 and outputs the adding result to an output terminal 11.

Title: Creation of new l-threonine-producing bacterium from esherrichia coli and production of l-threonine by the same bacterium
Inventor: URAJIMIIRU GEORUGIEITSUCHI DEB
IPC: C12R1/19
Filed: 1992-09-08
Abstract: PURPOSE:To provide the subject new recombinant plasmid DNA capable of creating a new threonine-mass-producing microorganism by transforming Bacillus coli and growing the transformant in a culture medium containing very low-cost molasses over many generations. CONSTITUTION:The objective recombinant plasmid DNA is obtained by integrating a threonine operon, i.e., threonine biosynthesis-related gene in which the attenuation region as a transcription-controlling region is missing into the downstream of the temperature sensitive C1 repressor, the PR promoter and the Cro protein-N terminal of a lambda phage and structured so that manifestation of the threonine biosynthesis-related gene may be controlled by the repressor and the promoter of the lambda phage. A plasmid containing the above- mentioned DNA is recommendably obtained by replacing the lambda phage PR promoter and the temperature sensitive C1 repressor with the transcription- controlling region in the threonine operon of plasmid pVIC 40.

Title: Magnet rodless cylinder and its stroke position adjusting body
Inventor: KAJITA AKIRA
IPC: F15B15/14
Filed: 1997-09-04
Abstract: PROBLEM TO BE SOLVED: To provide a magnet rodless cylinder with a wide application because a pair of follower bodies are movably followable independently from each other. SOLUTION: In a magnet rodless cylinder 1, follower bodies 31 and 32 are moved by a magnetic attractive force following pistons 21 and 22. The magnetic attractive force acts between a first piston 21 stored in a first cylinder tube 5 and the first follower body 31. Also a magnetic attractive force acts between a second piston 22 stored in a second cylinder tube 6 and the second follower body 32. In addition, a flow path capable of independently supplying and discharging drive fluid is disposed in both pressure working chambers RU1 and RU2 divided by the first piston 21 and those RL1 and RL2 divided by the second piston 22 so that both pistons 21 and 22 can be driven independently from each other.

Title: Dielectric gas type high-voltage breaker used for air blasting
Inventor: EDOMON TOURII
IPC: H01H33/70
Filed: 1989-09-14
Abstract: PURPOSE: To perform an operation with little energy regardless of interrupting current value by providing an interrupting chamber having a blowing cylinder and a set of secondary contacts together with an interrupting chamber for placing a fixed assembly having a fixed essential contact and a fixed arc contact and a movable assembly having a movable essential contact and a movable arc contact. CONSTITUTION: When a circuit breaker is opened, a movable part is driven by a tube 6, and when the contact is broken, an arc 50 sparks between arc contacts 4B and 5A. The increase in internal pressure of a chamber 20 keeps a piston 14 laid under the action of a spring 17 making contact with a part 16 as it is. The internal pressure of the chamber 20 is contact and low, and any excessive pressure is eliminated by opening a valve 14A. A pressure reduction caused within a capacitive part 35 opens a valve 44 to keep the internal pressure of the capacitive parts 35. Thus, no air energy is lost by suction. The arc 60 sparking between contacts 30 and 31 stops the piston 15 simultaneously with the arc 50 so that it is not moved to a part 16A. Thus, a circuit breaker which required a small operating energy even in the interruption of a weak current can be provided.
